Re: [undertow-dev] Some help on Reverse Proxy Server

Hi Stuart Thanks for this. I tried the example with a proxy server that has a valid ssl context, byte buffer slice pool, undertow xnio ssl with worker, and load balancing proxy client as per your example. Using 1.2.12.Final On the receiving webserver (which works fine with other https: and other SSL requests) I have enabled SSLCLientMode.Required and other settings similar to DefaultServer. This works when I go direct to the webserver in the browser - I can use it normally but when I use the proxy and issue a https request I get: ERROR proxy - UT005028: Proxy request to / failed java.io.IOException: overflow at io.undertow.protocols.ssl.SslConduit.doWrap(SslConduit.java:801) at io.undertow.protocols.ssl.SslConduit.write(SslConduit.java:336) at io.undertow.client.http.HttpRequestConduit.processWrite(HttpRequestConduit.java:321) at io.undertow.client.http.HttpRequestConduit.flush(HttpRequestConduit.java:573) at io.undertow.conduits.AbstractFixedLengthStreamSinkConduit.flush(AbstractFixedLengthStreamSinkConduit.java:229) at org.xnio.conduits.ConduitStreamSinkChannel.flush(ConduitStreamSinkChannel.java:162) at io.undertow.client.http.HttpClientConnection.initiateRequest(HttpClientConnection.java:299) at io.undertow.client.http.HttpClientConnection.sendRequest(HttpClientConnection.java:228) at io.undertow.server.handlers.proxy.ProxyHandler$ProxyAction.run(ProxyHandler.java:502) at io.undertow.util.SameThreadExecutor.execute(SameThreadExecutor.java:35) at io.undertow.server.HttpServerExchange.dispatch(HttpServerExchange.java:759) at io.undertow.server.handlers.proxy.ProxyHandler$ProxyClientHandler.completed(ProxyHandler.java:269) at io.undertow.server.handlers.proxy.ProxyHandler$ProxyClientHandler.completed(ProxyHandler.java:245) at io.undertow.server.handlers.proxy.ProxyConnectionPool.connectionReady(ProxyConnectionPool.java:292) at io.undertow.server.handlers.proxy.ProxyConnectionPool.access$800(ProxyConnectionPool.java:54) at io.undertow.server.handlers.proxy.ProxyConnectionPool$1.completed(ProxyConnectionPool.java:245) at io.undertow.server.handlers.proxy.ProxyConnectionPool$1.completed(ProxyConnectionPool.java:233) at io.undertow.client.http.HttpClientProvider.handleConnected(HttpClientProvider.java:163) at io.undertow.client.http.HttpClientProvider.access$000(HttpClientProvider.java:50) at io.undertow.client.http.HttpClientProvider$2.handleEvent(HttpClientProvider.java:126) at io.undertow.client.http.HttpClientProvider$2.handleEvent(HttpClientProvider.java:123) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at io.undertow.protocols.ssl.UndertowXnioSsl$StreamConnectionChannelListener.handleEvent(UndertowXnioSsl.java:312) at io.undertow.protocols.ssl.UndertowXnioSsl$StreamConnectionChannelListener.handleEvent(UndertowXnioSsl.java:294) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.nio.WorkerThread$ConnectHandle.handleReady(WorkerThread.java:324) at org.xnio.nio.WorkerThread.run(WorkerThread.java:539) Will the proxy forward the browser cert to the webserver or is there some other cause? I cannot share any code but any pointers are appreciated. Thanks Devl On Mon, Sep 14, 2015 at 2:17 AM, Stuart Douglas <sdouglas(a)redhat.com&gt; wrote:
